M1.0 solar flare erupted from AR 1760

Impressive M1.0 solar flare erupted at 20:00 UTC on May 31, 2013. Event started at 19:52 UTC and ended at 20:06 UTC. The source of eruption was Active Region 1760. This region is small but appears to have a large amount of shear in the central spot.

M1.0 solar flare was associated with Type II and Type IV Radio Emissions recorded at 19:57 UTC. Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event. Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

Earlier during the day, a prominence eruption was observed off the west limb. A Coronal Mass Ejection (CME) was produced, but luckily, it was directed away from Earth. A minor CME, unrelated to this event, swept past Earth and geomagnetic sudden impulse measuring 9 nT was detected at 16:18 UTC on May 31, 2013. The impact was weak.

There are currently 3 numbered sunspots on visible disk. All sunspots are stable and there is no strong activity expected. NOAA/SWPC forecasters estimate only 1% chance for M-class events.
